湖南报春苣苔的分布

Geographical distribution of Primulia tabacum in Hunan province

报道了报春苣苔在湖南的分布及生境。报春苣苔属为中国特有单型属,仅报春苣苔一种。该种分布狭域,生境要求严格,居群数量少,已被列为国家一级保护植物;长期以来一直认为报春苣苔为石灰岩地区特有植物,但在2011年4月在宜章丹霞植被考察中,在丹霞层间发现了该种的分布。分析了报春苣苔的分布,并预测其潜在分布区。

The distribution and habitat of Primulina tabacum in Hunan province were investigated and reported. Primulina Hance is a monotypic genus which is endemic to China, with only one species, to be named P tabacum Hance. It was thought to be distribute narrowly, demand a batter habitat, few individuals in population, and has been listed in ＂ the State First-class Protection Wild Plants＂ .
